CULTIVATOR.

JPECIFICATIQN forming part of Letters Patent No. 320,519, dated June 23,1885.

Application filed August 6, 1883.

To all whom, it may concern.-

3e it knownthat 1, WILLIAM S. WEIR, residing at Monmouth, in the countyofW-arren and State of Illinois, and a citizen ofthe United States, haveinvented certain new and useful Improvements in Cultivators, of whichthe following is a full description, reference being had to theaccompanying drawings, in which- Figure l is a top or plan View; Fig. 2,a cross-section on line a: 00 of Fig. 1; Fig. 3, a cross-section on liney 1 of Fig. 1; Fig. 4, a vertical section of the coupling on line 2 z ofFig. 1.

The object of this invention is to provide a simple and efficient meansfor holding the connecting-bow of a tongueless cultivator inasubstantially vertical position without adding to the cost of thecultivatorand without complicating the structure; and its natureconsists in holding the bow up by means of the coupling, and in theseveral parts and combinations of parts hereinafter set forth andclaimed as new.

In the drawings, A A indicate the dragbars forming the cultivator-beam;B, the bow; O, the coupling; a, the spindle; a, connecting-plate; 0,upper andlower coupling-plates; c, couplingbolt; d, circular projectionson the inner sides of the coupling-plates; 6, upper part of thecoupling-box; f, adjusting-holes; g, supporting ears or projections; h,lower half of thejournal-boX.

The drag-bars A A are formed by bending a metal bar of suitabledimensions around the coupling-pin 0 so as to form bars of unequallength, as shown, the outer ones, A, being the longest. These drag-barsare provided with suitable cultivator-shovels and guiding-handles, asshown, or in any well-known manner.

The bow or coupling arch B is also made of metal of suitable dimensions,and its ends are turned out horizontally and form either spindles a forattaching wheels, or plates a for attaching runners, as either wheels orrunners may be used. The horizontal portion is rounded to receive thecoupling 0.

The coupling 0 is made of plates 1), which are alike,and which areattached to the upper and under sides of the beams A A. Therear ends ofthese plates are furnished with projections b, which fit between thebars A A, and they are also furnished with circular projections d, whichfit into the boxes e h, and

(No model.)

form the pivot by which the beams have lateral movements. These twoplates are held together by a single bolt, 0, which passes through themin contact with the bend of the bars forming the cultivator-beam. Thelower boX, h, is a small one and moves with the under plate I) wheneverthe space between the beams is adjusted. The upper half-box, e, does notmove with the coupling when it is adjusted, but is provided with holesf, by means of which the adjustment of the space between them isefiected. The half-box e is forked at its inner end,forming the prongsg, which stand one on each side of the bow or arch B, and as they areabove the horizontal portion of the bow or axle they prevent the bowfrom falling down,as they hold or support it whenever it falls againstthe projection or ears 9 in either direction. This makes asimple andefficient support for the bow without adding to the number of partsforming the cultivator-coupling, and holding it in a substantiallyvertical position without any connection of the parts used forattachingthe team.-

The construction shown is the simplest and best form known to me; but itis evident that the box 6 may be made of a separate plate and be placedon top of the coupling, so as to give it a higher position and the bowor axle less leverage upon or against the ears; or the inner end of thebox may be turned up so as to bring the projections or ears 9 into ahigher position, and such other modifications as will readily suggestthemselves to any good mechanio may be used.

I have shown the bow in the form ofa con tinuous axle and without anyseparate device for attaching the team. Drag-bars may be directlyattached to the coupling 0, or such devices as are shown in my PatentNo. 274,070, March 13, 1883, may be applied, this part of the cultivatorbeing left to be of such construction, as may be desired.

It is also evident that the bow,instcad of be ing in the axle formshown, when other suitable devices are applied, may be jointed betweenthe bow and the coupling, and the bow still be held in a verticalposition by the same means; and I do not limit myself to the applicationof the half-box or forked plate to cultivator-beams having theconstruction shown,

nor to the specific form of coupling described,

2. The box or bar 6, having the ears 9 and adjusting-holesf and half-boxh, in combination with the plates 6, having the projections [5 e,substantially as and for the purpose specified.
